Saudi Arabia's King Salman has arrived in Tokyo with his 1,000-strong entourage making the first visit to Japan by a monarch from the nation in nearly five decades.

The 81-year-old king, who was greeted by Japan's Crown Prince Naruhito at Haneda airport, will meet Prime Minister Shinzo Abe on Monday and as he kicks off the Japanese leg of a broader tour of Asia.

Salman, who will visit 83-year-old Emperor Akihito on Tuesday, is travelling in style with his demands ranging from golden elevators to a fleet of hundreds of limousines.

Some 1,200 rooms at Tokyo's luxury hotels have been booked by the delegation for the three-night stay through Wednesday, according to local media, which has also reported that hundreds of limousines have been brought into the capital to accomodate the visitors.

This follows a lavish nine-day trip to Indonesia where the king ordered for a special toilet to be build in a mosque and a custom seat to be built in the House of Representatives.

Saudi Arabia is the largest provider of oil exports for Japan, which relies on Middle East for energy to power the world's third largest economy.

Japan hopes to use the visit to widen its relations with Saudi Arabia and help the country's efforts to diversify its economy, including exploring ways to increase Japanese investments in non-energy sectors such as manufacturing, according to officials.

King Salman's arrival marks the first visit to Japan by a Saudi leader since the 1971 visit to Japan by then-King Faisal.

King Salman himself, however, last visited Japan in 2014 as a crown prince.

The king is on a month-long tour of Asia, which has already taken him to Malaysia and Indonesia.

After Japan, he is scheduled to visit China and the Maldives.

Maldivian opposition parties on Friday raised objections to the planned visit and warned that they would stage protests over reports that Saudi business interests were buying an entire atoll in the politically-troubled Indian Ocean republic.
